SYNTHIA \(\rightarrow \)  Cityscapes: In this setting, we consider SYNTHIA [1]} as the souce and Cityscapes [2]} as the target dataset. SYNTHIA contains 9400 training images. However, unlike GTA5, due to lack of proper annotations for a few categories in SYNTHIA, we remove them from evaluation and report the results for 16 categories, following the literature. The validation set used for test-time adapttaion is again the 500 images commonly used for Cityscapes evaluation.
